TYPE 1000 TRANSDUCER Product Instructions - Valworx
TYPE 1000 TRANSDUCER Product Instructions PRINCIPLE OF OPERATION The Type 1000 transducer is a force balance device in which a coil is suspended in the field of a magnet by a flexure. Current flowing through the coil generates axial movement of the coil and flexure. The flexure moves against the end of a nozzle, and creates a back pressure in the nozzle by restricting air flow. This back pressure acts as a pilot pressure to an integral booster relay. Consequently, as the input signal increases (or decreases, for reverse acting), output pressure increases proportionally. Zero and span are calibrated by turning easily accessible adjusting screws on the front face of the unit. The zero adjustment causes the nozzle to move relative to the flexure. The span adjustment is a potentiometer that limits the flow of current through the coil. A thermistor circuit in series with the coil provides temperature compensation.
MOUNTING → The T1000 can be mounted at any angle, but should be calibrated after mounting. For maximum output pressure stability, the Type 1000 should be mounted vertically in a vibration free location or such that the vibration is isolated to the X and Z axis as shown in Figure 3. Pipe: Due to its light weight , the Type 1000 may be supported by the piping used for the supply and output.
Panel: ( with access to rear of panel) Attach transducer (See Fig. 3), to panel using two 10-32 screws and two threaded mounting holes on the back of the unit. Panel: ( with no access to rear of panel) Attach bracket (see Fig 1 and 3), to transducer using two 10-32 screws on the back of the unit and mount bracket to panel using four 8-32 screws.
Pipe mount U-Bolt Option: The pipe mounting hardware is not standard. Attach the bracket from Valve Mounting Kit, (order 010134000) to transducer using two 10-32 screws. Place u-bolt from 2” Pipe Mounting Kit (order 010-143-000) around pipe and through the bracket. Place lock washers and nuts on u-bolt and tighten. DIN Rail Mounting Kit Option: The DIN rail mounting kit is not standard. Order DIN Rail Kit (010115000).

The pipe plugs may be removed from the two auxiliary output ports for a pressure gauge or as an alternative output port. Note: On certain special models the pipe plugs are not factory installed, and must be installed air tight by the customer.

ELECTRICAL CONNECTIONS PRECAUTIONS TO BE OBSERVED DURING INSTALLATION The Bellofram T-1000 Transducers were tested at the EMC Test Centre, Dunfermline, Fife, KY11 5LB to the Electromagnetic Compatibility Directive effective January 1, 1996. The relevant EMC specifications tested were the following: EN 50081-1 (1992) and EN 50082-1 (1992). A Technical Construction File, Serial #107 was written and Certificate of Conformity issued by a Competent Body.
EN 50081-1 (1992): Test results confirmed that no precautions need to be observed during installation regarding electromagnetic emissions from the T-1000 Transducers. EN 50082-1 (1992): The following precautions should be taken during installation to maintain the advertised accuracy specifications for the T-1000 Transducers. The input wiring to the transducer should be isolated from other high voltage transient wiring. The momentary switching on and off of nearby relays, motors, or other high capacitive or inductive loads can have a minor effect on the terminal based linearity specification (1.0% of span, standard range models) for the T-1000. Any change in output pressure is minimal and momentarily, and is considered to be within the performance capabilities of the T1000. Use of a ferrite bead collar on the input wires entering the transducer is recommended should installation next to high electromagnetic interference be necessary.
Connect electrical signal to the wires exiting from the side of transducer through the 1/2” NPT conduit fitting. For DIRECT ACTING: ( where increasing the input signal increases output pressure ), connect the positive input signal to the black transducer lead, and the negative to the white transducer lead. For REVERSE ACTING: ( where increasing the input signal decreases output pressure ), connect the positive input signal to the white transducer lead, and the negative to the black transducer lead. Agency Approved Models may also be operated in either mode.

The plastic covers must be removed to gain access to the “ ZERO” and “ SPAN” adjustment screws. When calibration is completed, the covers should be replaced. Note: input percentage refers to the following examples: If 4 to 20 mA 0 % = 4 mA 25 % = 8 mA 50 % = 12 mA 75 % = 16 mA 100 % = 20 mA
if 1 to 10 VDC 0 % = 1.00 VDC 25 % = 3.25 VDC 50 % = 5.50 VDC 75 % = 7.75 VDC 100 % = 10.00 VDC
if 0 to 10 VDC 0 % = 0.00 VDC 25 % = 2.50 VDC 50 % = 5.00 VDC 75 % = 7.50 VDC 100 % = 10.00 VDC
If 10 to 50 mA 0 % = 10 mA 25 % = 20 mA 50 % = 30 mA 75 % = 40 mA 100 % = 50 mA
if 1 to 9 VDC 0 % = 1.00 VDC 25 % = 3.00 VDC 50 % = 5.00 VDC 75 % = 7.00 VDC 100 % = 9.00 VDC
If 0 to 5 VDC 0 % = 0.00 VDC 25 % = 1.25 VDC 50 % = 2.50 VDC 75 % = 3.75 VDC 100 % = 5.00 VDC
If 1 to 5 VDC 0 % = 1.00 VDC 25 % = 2.00 VDC 50 % = 3.00 VDC 75 % = 4.00 VDC 100 % = 5.00 VDC
Forward Acting 1. Apply the 0 % input signal to unit and adjust the "Zero" adjusting screw to the low setpoint output. Turn screw counter-clockwise to increase output. If there is no change in output, keep turning adjustment screw counter-clockwise until output begins to rise. It is imperative that the output pressure be closely monitored as turning the zero screw excessively could damage the flexure. 2. Apply the 100 % signal to unit and adjust "Span" adjusting screw until output is at the high setpoint. 3. IMPORTANT: On I / P (Current) input models, turn the “Span” adjusting screw counter-clockwise to increase output. On E / P (Voltage) input models, turn the “Span” adjusting screw clockwise to increase the output pressure. 4. Repeat steps 1& 2 until unit is calibrated. Reverse Acting 1. Apply the 0 % input signal to unit and adjust "Zero" adjusting screw until output reaches the high output pressure setpoint. Turn counter-clockwise to increase. 2. Apply the 100 % input signal to unit and adjust "Span" adjustment until output pressure is at the low setpoint. IMPORTANT: On I / P (Current) input models, turn the “Span” adjusting screw clockwise to increase output. On E / P (Voltage) input models, turn the “Span” adjusting screw counter-clockwise to increase the output pressure. 3. Repeat steps 1& 2 until unit is calibrated.
